[0002] In recent years, under the background of global economic integration, the shipping industry has developed rapidly, but the environmental pollution problems caused by it have also become increasingly prominent. At present, the fuel used by ships is mainly heavy oil, and its combustion products contain high concentrations of toxic gases, specifically SO2, NO2, NO, etc., which in turn have a bad and serious impact on the global climate environment.

[0003] For current purification devices, the simplest method is to use the adsorption effect of the filter plate to adsorb and purify the above-mentioned toxic substances. However, since the filter plate has filter holes and the filter holes are easily blocked, if they are not cleaned in time, the adsorption filtering effect will be affected. However, if the air is filtered during the working of the hull, the cleaned impurities will fall into the river and cause water pollution.

[0004] Therefore, it is necessary to design a high-efficiency ship exhaust purification device to solve the above problems. Utility Model Content
